I am currently living in Germany (American) and only started seriously hunting about 4 years ago. I have nt gotten "in to" Blaser but I am a serious Heym guy. I wish they were more popular in the US, they are terrific rifles. I am speaking of the Bolt Action and O/U doubles (and Drillings/BBFs) not the big game SS doubles. I have two SR21s, an SR30, two Model 26, one drilling and two Model 22(both .222 Rem under 20GA)
If you can find an SR 21 or 30 they are fantastic, accurate and reliable rifles. I have been to the factory several times and everything is fitted by hand. It is pretty amazing to see a sop full of master gunsmiths crafting thee rifles.
I have also had very god results with Barnes and Gecco Ammo. I also like Federal for what it is worth.
Buy a Heym, you won't regret it!
